Ko te Donpipe 301 te whakakotahi i nga polyols te turanga wai mo te whakamau paipa
IWHAKATOKANGA
Ko tenei hua he momo polyols whakakotahi ki te wai hei kaihoko hukahuka, he mea rangahau motuhake mo te PUF pakari hei whakaputa i nga putorino whakamaarama waiariki.Kei te whakamahia whānuitia i roto i nga putorino mamaoa, nga putorino hau rere, nga putorino hinu me etahi atu mara.Ko nga ahuatanga e whai ake nei:
(1) pai te rere, na roto i te whakarite i te ture kia rite ki nga diameters paipa rereke.
(2) teitei te mahi-a-te-te-mahi, he roa te tu i te 150 ℃
(3) tino pai te whakapumautanga o te ahua o te pāmahana iti
